Security device

Abstract

The invention relates to a security device for protecting an item from theft, comprising: at least one cable with two ends, a cable lock that is adapted for releasably attaching the two cable ends together by means of a locking device for forming a loop, the cable lock comprising a first cable end holding part and a second cable end holding part, which parts are adapted to releasably lock together with the locking device for forming the cable loop. The cable lock comprises a cable adjusting device, which is configured for forming an adjustable loop for the cable.

1 . A security device for protecting an item from theft, comprising: at least one cable with two ends, a cable lock that is adapted for releasably attaching the two cable ends together by means of a locking device for forming a loop, the cable lock comprising a first cable end holding part and a second cable end holding part, which parts are adapted to releasably lock together with the locking device for forming the cable loop, the cable lock comprises a cable adjusting device, which is configured for forming an adjustable loop for the cable, wherein the first cable end holding part comprises a biased drum rotatably mounted therein and operatively connected to one end of the cable for winding up of the cable, and a cable controlling device operatively connected to the biased drum wand operable to narrow the cable loop by releasing the drum for winding up the cable and to brake the unwinding of the cable such that the size of the cable loop is adjusted,
 wherein the cable lock comprises a two-part cable lock housing formed by the two cable end holding parts when locked together, and that each of the two cable end holding parts is functioning as a guiding member due to gravity when the cable lock is unlocked and the two cable end holding parts are detached.   
     
     
         2 . A security device according to  claim 1 , wherein one of the cable end holding parts comprises an alarm element adapted for triggering an alarm if the item is removed from a certain defined area. 
     
     
         3 . A security device according to  claim 1 , wherein the cable end holding parts are movably interconnected, such that the parts are displaceable in opposite directions in relation to each other to allow opening or closing of the cable loop for removing or securing the item when the locking device is released and fixed in relation to each other to close the cable loop for holding and securing the item from theft when the locking device is locked. 
     
     
         4 . A security device according to  claim 1 , wherein one cable end holding part has at least one male member extending in the direction of movement for the two cable end holding parts and facing at least one female member of the other cable end holding part, which female and male members are configured for displaceable interconnection in opposite directions. 
     
     
         5 . A security device according to  claim 4 , wherein one cable end holding part has two male members extending in the direction of movement for the two cable end holding parts, each male member facing a female member of the other cable end holding part. 
     
     
         6 . A security device according to  claim 2 , wherein one cable end holding part has at least one male member extending in the direction of movement for the two cable end holding parts and facing at least one female member of the other cable end holding part, which female and male members are configured for displaceable interconnection in opposite directions, wherein one cable end holding part has two male members extending in the direction of movement for the two cable end holding parts, each male member facing a female member of the other cable end holding part, and wherein a first male member is adapted to guide the movement of the cable end holding parts in relation to each other and to form part of an alarm circuit adapted to trigger an alarm if the cable lock is tampered with. 
     
     
         7 . A security device according to  claim 5 , wherein a second male member is adapted to guide the movement of the cable end holding parts in relation to each other such that the stiffness of the cable lock is increased to make the cable lock resistive against tampering. 
     
     
         8 . A security device according to  claim 1 , wherein the cable controlling device comprises an operable actuator with a braking member, the actuator being biased so that when in an inoperative position the braking member engages the biased drum to brake the unwinding of the cable and when the actuator is operated the braking member is moved out of engagement with the drum to release the drum for winding up the cable such that the size of the cable loop is adjusted. 
     
     
         9 . A security device according to  claim 1 , wherein the locking device in one of the cable end holding parts comprises at least one magnetically attractable leaf spring having an edge portion which in a rested state is engaged with the other cable end holding part. 
     
     
         10 . A security device according to  claim 1 , wherein the cable lock comprises an alarm circuit connected to the cable, configured to sound an alarm when the cable is cut off. 
     
     
         11 . A security device according to  claim 1 , comprising an electronic article surveillance (EAS) tag. 
     
     
         12 . A security device according to  claim 4 , wherein each cable end holding part is rounded.
